18 Now when all the people saw the thunder and the flashes of lightning and the sound of the trumpet and the mountain smoking, the people were afraid[1] and trembled, and they stood far off 19 and said to Moses, "You speak to us, and we will listen; but do not let God speak to us, lest we die." 20 Moses said to the people, "Do not fear, for God has come to test you, that the fear of him may be before you, that you may not sin." 21 The people stood far off, while Moses drew near to the thick darkness where God was.

Commentary on Exodus 20:18-21
(Read Exodus 20:18-21)
This law, which is so extensive that we cannot measure it, so spiritual that we cannot evade it, and so reasonable that we cannot find fault with it, will be the rule of the future judgment of God, as it is for the present conduct of man. If tried by this rule, we shall find our lives have been passed in transgressions. And with this holy law and an awful judgment before us, who can despise the gospel of Christ? And the knowledge of the law shows our need of repentance. In every believer's heart sin is dethroned and crucified, the law of God is written, and the image of God renewed. The Holy Spirit enables him to hate sin and flee from it, to love and keep this law in sincerity and truth; nor will he cease to repent.
